Regarding juries, I've never seen anything to support an education bias in actual jury composition, and what evidence I've seen instead points to the opposite. There does seem to be plenty of evidence of racial bias.
Now, to be clear, there is probably some reason you are summarily screened out during voire dire. Statistically, it probably has more to do with your race than your education level. That's all.
That said, I think it's always interesting insight when people share the stories they tell about themselves. Personally, I was dismissed from a jury because I'm so damned good looking. They took one look at me and thought I'd be too distracting.
Steve,
Twice Defense attorneys did not let me finish once I was half way through Engineer.
One time a Judge covering for another judge who had a family emergency, asked, and with the number of police, doctors, nurses, and engineers, he went back and told everyone in the court room to consider settling or they would begin jury selection.
None of the Defense attorneys saw me for race or size.
There are other situations that fit in between.
I was a witness for an accident where someone died.
I testified for the prosecution.
And before the defense could go, the Judge continued to ask me questions to get details of the intersections and timed lights and such.
The Defense then asked me more questions. He even commented that for a Prosecution witness for Man-Slaughter , I was sure helping his case. I smiled and turned to the judge and asked if I could reply, he smiled and yes.
I told him, I was presenting the data as I saw it, and knew it to be for visibility and such.
The Widow, understood it was an accident.
The prosecution asked for conviction.
The Defense attorney and client had done judge and no jury.
He had spent months in jail as he could not afford the bail. His ex-wife ( as they divorced while he was in jail for legal reasons ) was trying to keep the house and their one vehicle left going.
The judge, convicted with time served, and released that day.
So my experience is not the some total the world or USA or Michigan or even my county, it is that the evidence was not about being White, or Non White, it was about being an engineer.
Good or bad that was my experience.
